Presence detection of low-contrast targets in a weld shop
February 2018, Sensors & Transducers
Environmental conditions in automotive weld shops can adversely affect sensor performance and longevity. Frequent stops in production processes may be required to clean, maintain, and replace damaged or dirty sensors. Challenges include:
• Weld splatter can burn sensor lenses, causing permanent damage.
• Accumulation of dust and residue from welding fumes on the sensor lens gradually degrades performance and reliability.
• Low-profile, low-contrast targets can be very difficult to detect.
Solution: Q4X laser distance sensor
• 316L stainless steel housing and an add-on aperture lens kit made of borosilicate glass protects the sensor and lens, ensuring a long working life.
• Best-in-class excess gain burns through dust and residue on the sensor lens to provide reliable performance with minimal maintenance downtime.
• IO-Link enables remote configuration, monitoring, and extended diagnostics to simplify installation, maintenance, management, and sensor replacement.
• Sensor detects sub-millimetre changes in distance to verify part presence or positioning, regardless of colour or reflectivity of object and background.
• Compact sensor installs easily into space-constrained applications.
